"content": "## AI customer care chatbot for Vietnamese SMEs with Zalo Bot, Gemini and Google Sheets CRM\n\n### How it works\n1. The Zalo Bot Trigger receives every text message sent to your bot.\n2. The customer is looked up in Google Sheets CRM; new customers get a welcome sticker and greeting.\n3. A Switch node detects intent by keyword: menu, products, pricing, or human escalation.\n4. Known intents trigger specific handlers (text menu, product photo, pricing list, or escalation log).\n5. Unrecognized messages go to Google Gemini for a context-aware Vietnamese AI reply.\n6. Every conversation is logged to Google Sheets for review and training.\n\n### Setup steps\n- [ ] Self-hosted n8n required (community nodes cannot be installed on n8n Cloud)\n- [ ] Install community node `n8n-nodes-zalo-platform` via **Settings > Community Nodes**\n- [ ] Create a Zalo Bot via **Zalo Bot Manager** in the Zalo app to get the Bot Token\n- [ ] Create a Google Gemini credential (free tier from [Google AI Studio](https://aistudio.google.com))\n- [ ] Copy the [Google Sheets CRM template](https://docs.google.com/spreadsheets/d/1e9155FKWikWTADXWssAdYvOq7g8l3N4NvhnxQXo9EFc/edit?usp=sharing) via **File > Make a copy**\n- [ ] Create a Google Sheets credential and assign it to all Sheets nodes\n- [ ] Paste your Sheet ID into the **Set Configuration** node `googleSheetId` field\n- [ ] Update **Set Configuration** with your business name, product photo URL, pricing, and hotline\n- [ ] Activate the workflow\n\n### Customization\n- Add more intents to the Switch node (booking, refund, shipping)\n- Replace Google Sheets with Airtable, Notion, or Postgres\n- Send promotional stickers on seasonal events\n- Add business-hours check for different out-of-office replies\n- Switch Gemini for OpenAI, Claude, or a self-hosted model\n\n### Need help?\n- [Zalo Bot node setup guide](https://thenexova.com/n8n-zalo-bot-node-complete-setup-and-operations-guide/)"
